What is Tandem OLED

Tandem OLED: A New Era in Display Technology

Tandem OLED panels stack two layers of RGB organic light-emitting diodes, creating a structure that offers significant advantages over traditional OLEDs. This dual-layer configuration enhances brightness, doubles the lifespan, and reduces power consumption by up to 40%. Originally designed for the demanding quality requirements of automotive industrial displays, Tandem OLED is now being tailored for high-usage IT products like laptops.

Superior Brightness and Efficiency

The key innovation of Tandem OLED is the use of two OLED panels 'in tandem' to combine their light output. Unlike traditional single-layer OLEDs, this approach does not aim to double the resolution but to significantly increase light output and efficiency. By stacking two layers of OLED pixels, Tandem OLED panels can produce much more light, addressing the common issue of insufficient brightness in OLED screens.

Addressing the Brightness Challenge

Historically, OLED screens have struggled with brightness limitations, especially in larger devices. This is due to the nature of OLED pixels, which generate both light and color. The introduction of Tandem OLED technology marks a significant improvement, enabling screens to achieve brightness levels previously unattainable by traditional OLEDs. For instance, the new iPad Pro’s Tandem OLED screen reaches peak HDR brightness of 1,600 nits and fullscreen HDR brightness of 1,000 nits, far surpassing the brightest OLED TV measurements.

Tackling Burn-in Issues

Another persistent problem with OLED screens is burn-in, where static images can become permanently imprinted on the display. This issue is exacerbated by the need to increase brightness, which generates more heat and accelerates burn-in. Tandem OLED technology addresses this by distributing the light output across two layers, reducing the strain on each layer. This not only mitigates burn-in but also extends the overall lifespan of the screen.

Enhanced Durability and Lifespan

Tandem OLED panels offer double the lifespan of traditional OLED panels. By using two layers of pixels, each layer can operate at lower brightness levels for standard usage, reducing heat generation and wear. This results in screens that maintain their performance and image quality for longer periods, making them ideal for high-usage devices like laptops.

Power Efficiency: A Key Advantage

One of the standout benefits of Tandem OLED technology is its power efficiency. By effectively doubling the light output without a proportional increase in power consumption, Tandem OLED panels can reduce energy use by up to 40%. This is particularly beneficial for portable devices, where battery life is a critical factor. The reduced power consumption also contributes to the overall thermal management of the device, enhancing its reliability and user comfort.

Slimmer and Lighter Designs

The dual-layer structure of Tandem OLED panels is not just about performance improvements; it also enables slimmer and lighter designs. The new Tandem OLED panels are 40% thinner and 28% lighter than their traditional counterparts. This opens up new possibilities for creating more portable and sleek laptop designs without compromising on display quality.

Meeting the Demands of Modern IT Products

The first application of Tandem OLED technology in laptop panels is a significant milestone. Engineered specifically to meet the unique demands of laptop usage, these panels offer a superior user experience. The enhanced brightness, reduced power consumption, and extended lifespan make them ideal for the rigorous demands of modern IT products.
